I have a 2GM and my manual calls for 1.9 litres which is about 1.8 us quarts. Of course the correct amount could vary depending on when built and any factory changes to the pan etc.
It is definately not OK to run an engine with too much oil. I would confirm that you have the correct manual and then trust it. Your dip stick may not be the original one and therefore wrong.
